CUSHION STRUCTURE.

Specification of Letters Patent.

Patented Feb. 22, 1916.

Application filed September 20, 1915. Serial No. 51,588.

To all whom it may concern:

Be it known that I, FRANK PrDABCY, a citizen of the United States,residing at Kalamazoo. Kalamazoo countv, State of Michigan, haveinvented certain new and useful Improvements in Cushion Structures, ofwhich the following is a specification.

This invention relates to improvements in cusion structures.

The main objects of my invention are First, to provide. an improvedcushion structure in which the upholstering is secured without thenecessity of stitching or sewing. Second, to provide an improved cushionstructure in which the upholstering cover is provided with a metalbinding edge so that it is protected from wear at the bottom of thecushion where the cushion rests upon a seat. T hird, to provide animproved cushion structure having these features which is attractive inappearance and at the same time verv economical to produce, the partsbeing easily and quickly assembled by unskilled labor.

Further obiects, and obieots relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanving drawin forming a part of thisspecification, in which:

Figure I is a detail inverted view of my improved spring cushion. Fig.II is a detail vertical section from front to rear of my improvedcushion. Fig. III is an enlarged detail section on a lineCOI'IQSDOHdlIlg to line 3-3 of Fig. I. showing details of the securingmeans. Fig. IV is an enlarged detail section on a line corresponding toline H of Fig. I, showing the arrangement of the covering, whichprovides a buffer for the cushion. Fig. V is a detail perspective viewof one of the cover retaining or binding members before it is applied tothe cushion. Fig. VI is-a detail vertical section corresponding to thatof Fig. II of a modified form of my invention.

In the drawing similar reference characters refer to similar partsthroughout the several views and the sectional views are taken lookingin the direction of the little arrows at the ends of. the section lines.

Referring to the drawing, the cushion springs 1 are mounted on the sheetmetal cross bars or supports 2, the details .of the mounting not beingillustrated. The ends of the cross bars are rigidly secured to thebottom border frame 3 by folding the ends 4: of the cross bars aroundthe border frame. The upper ends of the outer springs are connected tothe top border frame 5 by means of the coils or clips 6. The tops of thesprings are also connected to each other and to the frame by means ofthe cross wires 7 and 8, thus supporting the springs in an uprightposition and providing a network for supporting the upholstery.

The backing 9 of the upholstering 'is drawn over the springs with itsskirt or side portions 10 embracing the sides thereof and wrapped aroundthe bottom border wire at 11. The outer cover 12 is arranged over thefilling 13 and the edges of its side or skirt portion 14 wrapped overthe backing around the border wire, as at 15.

The filling 13 is preferably arranged between the backing and the coverat the front end of the cushion, see Fig. II. 'The covering and backingare secured to the bottom frame wire and a binding is provided for thecover by means of the binding or securing members 16. These binding orsecuring members 16 are formed of sheet metal and are first bent into aU-shape, *'as shown in Fig. V, and arranged over the border wire withthe backing and covering wrapped thereon and clamped upon the same intothe cylindrical shape shown in Fig. III, the distance between the edgesof the binding members being less than the diameter of the border wireswith the cover wrapped thereon so that it is quite impossible to pullout the edges of the cover. The parts are offectively secured togetherand also a metal binding is provided for the cover.

The corners of the frame border members are preferably curved as shownin Fig. I, the corner binding members being curved to correspond. Theedges of the backing and covering are preferably lapped under the endsof the cross or spring supporting bars to provide buffers 17, whichserve to prevent rattling of the cushion in the event that it should beloose in its seat.

It is quite common practice, particularly the seats for retaining thecushions.

viatingthe necessity for sewing or the pro-' ,viding of finishingstrips, and at the same time secure the covering even more effectivelythan by sewing. A further advantage is that-the work can be quickly doneby unskilled workmen, the binding members being rapidly applied by meansof pliers. 1 In the modification shown in Fig; VI the backing 18 andc0ver 19 are secured to a skirt portion 20 by the seam 21. The skirtportion. is secured to the border frame the same as in th structureshown in the other figures.

I have illustrated and described my im provements in two forms in whichI have embodied the same. I have not attempted to illustrate'oredescribe various modifications and adaptations which are possibleand might be desirable for the manufacture of cushions for 'difi'erentpurposes, as I believe the disclosure made will enable those skilled inthe art to embody or adapt the same as circumstances may renderdesirable.

Having thus described my invention, what I claim as new and desiretosecure by Letters Patent, is:

1. In a spring structure the combination of thebottom border frame ofwire, said frame being curved at the corners, coiled springs, springsupporting bars secured to said border wire, a cushion cover having itslower edges wrapped around said border frame, and binding members ofsheet metal curved in cross section disposed to embrace Copies of this,patent may be obtained for five cents each, by addressing the"Commissioner ctlatents said bottom border frame and said cover, thesecuring members at the corners being curved to correspond with thecurves of the corners of the border frame, the distance between theedges of said securing members being less than the diameter of theborder frame whereby the cover is secured to the frame and a metalbinding edge provided forthe supporting bars to embrace said bottomborder frame and said cover, the dIStflIlCB between the edges of saidsecuring members being less than the diameter of the frame and a metalbinding edge provided for the cover, the cover being lapped below theends of said cross barsto provide buflers.

3. In a spring structure, the combination of the bottom border frame ofwire, coiled springs, spring supporting bars secured to said borderwire, a cushion coverhaving its lower edges wrapped around said borderframe, and binding members of sheet metal curved in cross sectiondisposed to embrace said bottom border frame and saidcover, the

distance between the edges of said securing members being'less than'thediameter of the border frame whereby the-cover is secured to the frameand a metal binding edge provided for the cover.

In witness whereof, I have hereunto set my hand and seal in the presenceof two witnesses,
